Metacommunities and biodiversity patterns in Mediterranean temporary ponds: the role of pond size, network connectivity and dispersal mode 

Tornero Pinilla, Irene (Date of defense: 2020-03-13)

We sampled the macrofaunal metacommunities in four networks of Mediterranean temporary ponds covering a wide range of pond sizes and different spatial extents. 1) In the smallest pond network, pond size ...

Reproductive and condition status of “cold water” marine fish: new insights from a changing environment 

Serrat Llinàs, Alba (Date of defense: 2019-04-10)

Exploited marine fish species with an affinity for cold waters inhabiting close to the warmer edge of their distribution area are exposed to stress caused by fishing and climate change. Three case ...
